# Effect of thermocycling, mechanical loading on longevity of endodontically treated teeth restored with zirconia, fiber posts

## TL;DR

This study compares zirconia and fiber posts in restored teeth, finding that fiber posts offer better long-term stability under oral conditions.

## Contribution

The novel contribution is identifying fiber posts' superior long-term performance under simulated oral fatigue conditions.

## Key findings

- Zirconia posts showed higher initial bond strength.
- Fiber posts maintained better stability after thermocycling and mechanical loading.
- Fiber posts may improve clinical longevity of dental restorations.

## Abstract

The comparative performance of zirconia and fiber posts in endodontically treated teeth under simulated oral conditions, show
significant differences in fatigue resistance and bond strength degradation. Zirconia posts initially exhibited superior bond strength;
fiber posts maintained better long-term stability under thermocycling and mechanical loading conditions, with implications for clinical
longevity and restoration success rates.
